Hi all. I currently have a berg HS410 cab (4ohm) I'm using with a Thunderfunk 750a. Thinking of picking up a deal on a berg HS210 (8 ohm) to use for another practice space and smaller gigs. Potentially both for the big gigs. 1) is it safe to run the hs410 + hs210 with the thunderfunk 750a? I notice really the only difference besides ohms is the cab efficiency at 104 vs 98. The cab depth is slightly smaller on the hs210. 2). Would it just sound like an "HS610"? Would be nice for bigger gigs where I may need like an 810. 3). The thunderfunk would be running at 2.7 ohms. Ok?
